a all whom it may concern:

Be it known that I, PAUL Sonoo, a citin of the Kingdom of Denmark,residing 1 Copenhagen, in said Kingdom, have in- :nted certain new anduseful Improveents in Apparatus for Absorbing Gasespr apors, of whichthe following is a specifi- LtlOll. t v

This invention relates to an improved oparatus for absorbing gases orvapors by itlmate contact with a minutely-divided Jsorption liquid,while at the same-time the irrymg along of small particles of theabrption-liquid by the current of gas or vaors is avoided.

The subject-matter of the invention is lOWIl in the accompanyingdrawing, in hich- F' ure 1 represents aside-elevation of the bso fiierfor a vacuum refrigerating maiine, Fig. 2 is a vertical central sectionlrough the absorber, drawn on a larger :ale, and Fig. 3 is a detailhorizontal secon through a portion of the same, on line .B,.Fig. 2.

Similar reference characters indicate corasponding parts throughout thefigures.

Referring to the drawing, the vessel 3 of ie absorber is filled withabsorption llqllld, or instance, sulfuric acid, up to the level 1. Inthe upper portion of the vessel 3 is rranged a hollow body 7, 8, 10,which is made slidable by means of a tube 1 in a tuflin -box 6 in thetop 4 of the absorber, so 5 to e vertically adjustable in the vessel Thebottom of the hollow body 8 s1 perforated and filled up to a certaineight with ;1ass pearls, or, as shown in the drawing, vith a pluralityof upright glass tubes 9 rhich are tapermg at their lower ends.Thera'ses or vapors, as, for instance, the water- 'apors from the cooler12' of the vacuxm' refrigerating machine are conducted hrough the pipe 1into the hollow body 7, 8

It. is obvious that by this arrangementand the process of dilfusing the absorption-liquid in very thin filmsover a large contact-surface, a considerable quantity of gases or vaporscan be quickly and reliably absorbed by the'liquid without producing theobjectionable carrying along of any traces or particles of theabsorption liquid through the pipe 2 to the air-pump 14.- As soon as theabsorption-liquid loses its capacity for abso tion by saturation theprocess is interrupt and the hollow body with its contact'surfacesimmersed again into the absorption liquid and withdrawn from the same,after which the process of absorption is continued. a

-When it should be necessary to cool the vessel 3, a jacket 5 or anyother cooling device, is arranged around the same through which coolingwater is conducted. In place of making the hollow body movable, it canbe made stationary, and, on the otherhand, the vessel containing theabsorption liquid can bemade-movableyso as to renew from time to timethe covering of the surfaces of the hollow body with the absorptionliquid." y

I Having thusdescribed my invention, I claim as new and desire to secureby etters 1. An apparatus for the absorption of gases or vapors, whichcomprises a vessel for the absorption liquid, a hollow body arranged inthe same and adapted to be immersed in the liquid, said hollow body be-.

and means for causing the passage of said gases or vapors downwardlythrough said hollow body and over said contact bodies;
